Hymen

I do believe I've figured out what part my vagina is the hymen. Which also seems to be the source of the pinching with my recent silicone dildo which is my largest.

It is this small piece of skin at the base of my vagina that I can in fact hold between to fingers, but when I use my silicone dildo, it gets pulled taught, and causes the pinching sensation. Clearly I need apply more lube directly there.

I have found mine and it's pretty thick. It actually causes problems during sex for me. But, you can go to a OBGYN and request to have it removed. They just cut it off and you get to go on with your life. I'm considering it as I am about to have my first child and I'm afraid it'll get in the way. ^^
